CUSTOMER WIRING CONNECTIONS
Customer wiring connections for
120
volts only are shown at right.
A 3-wire cable should be used.
Connect two alternator T2 wires to
one cable wire. Connect one alter­
nator Tl'wire to a second cable
wire. The third cable wire should'
be connected to the grounding lug,
as shown at right.
NOTE
Panel output wiring can be reconn­
ected to supply a dual voltage of
120/240 volts.. See Section 2. A 4-
wire cable is required.when supply­
ing dual voltage. __________
VOLTAGE REGULATOR
The Voltage Regulator used on the TXP provides a constant voltage to
frequency ratio of 2 to 1, That is, when alternator frequency is 60 Hz,
voltage output will be 120 volts a-c ( + 27o). If frequency should drop
to 55 Hz, output voltage would also drop, to about 110 volts a-c.
The Voltage Regulator Assembly for
the Model 6931-1 TXP is shown at
right. Be sure to check the wiring
diagram for the specific model in­
volved. The following CHART lists
Regulator wires and their function.
